It would be very helpful if we could get some profiling information on some
of the more intensive routines, in order to get a better idea of where the
problems lie. I do know that we have a problem with virtually all of our
image drawing code (basically, just a bunch of for() loops).
Unless you need to draw transparent bits (from GIF, PNG or XPMs) or have to
stretch images on the fly, I would recommend that you draw all of your
images to a offscreen pixmap, and then blit them from there. Until we get a
group of blitters in place to better handle images, this will be your best
bet.
